Design and Analysis of E-Shape Sierpinski Fractal Antenna

An E-shape Sierpinski fractal antenna has been designed & analyzed in this paper using High Frequency Structure Simulator (HFSS). The Sierpinski carpet geometry has been modified to design the antenna upto 3rd iteration using 1.8GHz operating frequency. The space filling property of fractal and coaxial probe feed are used to design above said antenna. The feed position is set manually for matching input impedance, positive gain and low return loss. Performance has been analyzed in terms of return loss, VSWR, peak gain, peak directivity and radiation efficiency in the 1GHz to 10GHz frequency range.
